Wind energy has been extensively used on a global scale. With the development of offshore wind power, the reliability of offshore wind turbines is increasingly important. In this paper, the semi-submersible floating wind turbine is divided into four subsystems, including mechanical, electrical, transmission and electronic control systems. Reliability allocation is conducted for the floating wind turbine by feasibility of objective method. On this basis, the fault tree is built for the floating wind turbine with qualitative analysis. Combining the results of reliability allocation with fault tree analysis, we suggest that mooring system, lubrication system of gearbox, cooling system and yaw system ought to be given particular attention in the design of floating wind turbines.
